Hi fredj<br>
<br>
Yes. I have done exactly same as you say.<br>
<br>
But are you using tilecache_seed.py code to seed? if yes, look at the
output screen, you see that tiles are generated one by one..<br>
in my case, each tile takes 1 second to generate and we have like 40
layers in our map file..so I know it needs high computing power to send
each request seperately to tilecache...I was hoping that
tilecache_seed.py could jump another 11 tiles and request like 1 - 12 -
23 - 34 - 45 ....<br>
because when it calls for 1, it generate all 121 tiles around it...when
it calls 12, it generate all tiles around 12...and so on..<br>
so it doesn not need to call for: 1-2,3,4,5,6,7,8..........<br>
<br>
thanks<br>

Hi,<br>
<br>
The meta tiling system works for me with the trunk version [1].<br>
Make sure you have the:<br>
metaTile=true<br>
metaSize=11,11<br>
in your layers options.<br>
Meta tiling is off by default even if you have a metaSize.<br>
<br>
Regards,<br>

PS: lucky you; I have more that 9'000'000 tiles in my last level :-)<br>
